Dark matter (DM) has been one of the biggest mysteries in astroparticle physics for the last three decades now. Despite there being a plethora of observational and gravitational evidence pointing towards its existence, we still have not been successful in directly detecting DM in any terrestrial or space-based experiment. In this talk, I shall take you along in my journey through dark matter research, wherein I would discuss my role in setting up a new DM detection experiment in India and my work with dual-phase xenon TPCs. I would talk on my research in background measurement and simulation at a new underground lab in India, and characterization of scintillators and SiPMs for the proposed DM search experiment. I would then discuss my works in the XENON collaboration in calibrating the XENONnT detector for low energy nuclear recoils, and exploring the reach of dual-phase xenon TPCs for physics, for example supernova neutrino detection and solar pp neutrino measurements with present and future generation detectors (XENONnT and XLZD), an effort that has in its core the extension of DM search to unexplored parameter spaces by understanding and suppressing intrinsic backgrounds of the dual-phase xenon TPCs.
